The Mapping operator can be used to assign UVW values to particles.
By querying closest points on object surfaces, you can assign corresponding mapping values to particles.
Input object list: the list of scene objects from which UVW values will be taken.
Sample type: controls which sampler will be used to determine closest-object proximities for particles.
All available channels: when enabled, UVW values from all available surface channels will be applied to corresponding particle UVW channels.
Map Channel: the individual map channel to extract UVW values from.
Same as source: when enabled, the UVW data will be assigned to the same particle UVW channel it was taken from on the source object.
Map Channel: the particle UVW channel to assign the UVW data to.
Assigns mapping values from particle custom data channels.
Disabled: mapping from custom data is disabled.
Mapping from float: mapping values will be taken from a particle’s custom float data channel.
Mapping from vector: mapping values will be taken from a particle’s custom vector data channel.
Channel: the channel to take the custom data value from.
Enable: controls whether mapping values will be converted into a value between 0 and 1, based on a target value range.
Min: the minimum value of the range.
Max: the maximum value of the range.
Invert: inverts the resulting ratio.
UVW Axis X/Y/Z: controls which axis of the particle’s UVW value to assign custom float data values to.
Map Channel: controls which particle mapping channel to assign the UVW value to.
Allows you to clamp mapping values to specific min/max values.
Enable clamping: controls whether clamping will be enabled.
X/Y/Z: the min/max x/y/z values to clamp each particle’s UVW values between.
All channels: clamping will be applied to all mapping channels.
Map channel: the specific mapping channel to apply clamping to.
Allows you to shift particle mapping values between channels.
Disabled: no shift operation will be performed.
Copy: particle mapping values will be copied from a source map channel to a target map channel. The source channel value will be retained.
Move: particle mapping values will be moved from a source map channel to a target map channel. The source channel value will be removed.
Swap: particle mapping values will be swapped between a source map channel and a target map channel.
Source channel: the source map channel.
Target channel: the target map channel.
